I'm looking for some good overnight hikes that don't require me to drive out to the SNP. Having lived in Centreville before I moved to Richmond, I have heard of the Bull Run Occoquan trail but I have never known anyone that has hiked it. Has anyone out there hiked it? If so, I know it's 18 miles and do able in a long day, but do they allow camping to break it up into an easy 9/9 over nighter? I'd love to set out and use it as a shakedown before my thru in March.
